G418 (Geneticin) : selection antibiotic, cell culture tested, sterile reagent
G418 also known as G-418, G418 sulfate or Geneticin is an aminoglycoside antibiotic produced by Micromonospora rhodorangea.
G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells.
Resistance to G418 is conferred by the Neomycin resistance gene (neo) from Tn5 encoding an aminoglycoside 3'-phosphotransferase, APH 3' II.
Selection in mammalian cells is usually achieved in 3 to 7 days with concentrations ranging from 400 to 1000 µg/ml.
Cells that are dividing are affected more rapidly than non-dividing cells.
